Hello Andrey,

I am not sure but I suppose this is connected with the changing in function arguments bug discussed in Functions behave differently in 0.9

Here is an example using integration.
1. This is the calculation at the beginning

2. This is when recalculate (F9)

Here is the sm file recalculate problem
It reported that variable "x" is not defined (actually, it should be that way). Do not understand what happened here?

Regards,
Radovan
